What is combustion chamber in gas turbine?
What is combustion chamber in gas turbine?
A combustor is a component or area of a gas turbine, ramjet, or scramjet engine where combustion takes place. It is also known as a burner, combustion chamber or flame holder. In a gas turbine engine, the combustor or combustion chamber is fed high-pressure air by the compression system.
How does a compressor work in a gas turbine?
As hot combustion gas expands through the turbine, it spins the rotating blades. The rotating blades perform a dual function: they drive the compressor to draw more pressurized air into the combustion section, and they spin a generator to produce electricity.
What are the 2 types of compressor used in a gas turbine engine?
Compressor Types The two principal types of compressors currently being used in gas turbine aircraft engines are centrifugal flow and axial flow.
What is the use of combustion chamber?
A combustion chamber is part of an internal combustion engine in which the fuel/air mix is burned. For steam engines, the term has also been used for an extension of the firebox which is used to allow a more complete combustion process.
What are two types of combustion chamber?
There are two combustion chambers one is auxiliary combustion chamber and the other is the main combustion chamber. This auxiliary chamber is smaller in size than the main combustion chamber and is called the pre-combustion chamber. The fuel is injected in the pre-combustion chamber where is partly burned.
What is compressor part of the gas turbine?
The compressor section of the gas turbine engine has many functions. Its primary function is to supply air in sufficient quantity to satisfy the requirements of the combustion burners. Air is often bled from the final or highest pressure stage since, at this point, pressure and air temperature are at a maximum.
Which compressor is used in gas turbine plant?
Multistage axial flow compressor
Which type of compressor is used in a gas turbine plant? Explanation: Multistage axial flow compressor is the compressor in practical usage in a gas turbine plant.
What are the parts of combustion chamber?
The combustion chamber of a modern turbine typically consists of a cylinder with a second smaller cylinder called the liner inside it. A fuel air mixture passes into the mouth of the liner and additional air may pass around the outside of it, between the liner and the outer cylinder to keep the liner cool.
Which type of compressor is generally used in gas turbine?
axial flow compressor
The principal type of compressor used nowadays, in the majority of the gas turbine power plants are especially in aircraft applications, is the axial flow compressor.
Where is combustion chamber used?
What happens to the air after compression in a wind turbine?
After compression, the air goes into the combustion chamber where compressed air is mixed with fuel and burnt, so that the temperature of burnt gases increases up to the level of turbine inlet temperature (TIT).
What are the characteristics of combustion chamber?
The design of combustion chamber involves the shape of the combustion chamber, the loshape of the combustion chamber, the location of the spar cation of the sparking plug and the disposition king plug and the disposition of inlet and exhaust valves.
How does temperature affect gas turbine power output?
Gas turbine output is a strong function of the ambient air temperature with its’ power output dropping by 0.5-0.9% for every 1oC rise in ambient temperature due to air density becoming smaller on hot days. Inlet air cooling is one of the options for maintaining the temperature of admitting air in desired limits.
How much does temperature and humidity affect the performance of compressors?
The variation in temperature and humidity of atmospheric air significantly affects the plant performance of naturally aspirated compressors in gas turbinebased installations. oC to more than 45oC and relative humidity variation from less than 24% to more than 81% in tropical countries.
